South Korea to Tax Crypto Gains Over 2.5M Won at 22% Starting 2027

South Korea will begin taxing cryptocurrency gains at a combined rate of 22% starting Jan. 1, 2027, the government confirmed — ending months of speculation that the long-delayed levy might be pushed back again. Deputy Prime Minister and Finance Minister Koo Yun-cheol announced the schedule at a National Assembly Finance and Economy Planning Committee meeting on July 29, saying the government is “pushing forward with the plan to tax cryptocurrency starting next year as scheduled.” Under the Income Tax Act, income from transferring or lending virtual assets will be classed as “other income.” Annual gains above 2.5 million won (about $1,740) will be taxed at a 20% national rate, with a 2% local tax bringing the total to 22%. Investors whose annual gains remain below the 2.5 million won threshold will not owe tax. Taxpayers are expected to file their first returns in May 2028 for income earned in 2027. Background and legislative path - The levy was first approved in 2020 and originally slated to take effect in January 2022. Implementation was postponed multiple times — initially to 2025 — and a December 2024 amendment moved the deadline to 2027. The National Assembly’s recent revisions to the Income Tax Act ratified that schedule. - A separate opposition bill, introduced in March, seeks to remove crypto income from the Income Tax Act entirely. That proposal was referred to a subcommittee on July 29, leaving open the legal possibility of repeal or another delay before the end of 2026. Market and policy implications - Opposition lawmakers raised immediate concerns about the tax design. People Power Party lawmaker Kim Sang-hoon argued that the framework won’t allow investors to offset losses against future gains, removing a common tax flexibility found in other jurisdictions. He warned that this could push trading activity off domestic exchanges (including Upbit, Bithumb, Coinone and Korbit) and into overseas centralized platforms, decentralized finance venues or peer-to-peer markets — reducing domestic trading volumes and tax visibility. - Koo acknowledged those concerns but said moving crypto into a capital-gains-style regime would require a broader overhaul of South Korea’s tax treatment for financial markets. He suggested the government may revisit the rules after gathering operational data once the system is in place. Regulatory context and next steps - The tax decision arrives while lawmakers and industry groups continue negotiating a wider digital-asset framework and stablecoin rules. On July 29, Hashed Open Research and the Solana Policy Institute published a policy paper urging interim licensing guidance for stablecoins — covering issuance, payments, permitted activities and treatment of foreign-issued tokens — while the Digital Asset Basic Act is still being drafted. Those recommendations are advisory and do not change current law, but proponents say delays in formal legislation could leave firms unsure about issuing or using won-backed stablecoins. - South Korea is also ramping up state-backed technology investment. The government approved plans for a 20 trillion won account under the Korea Investment Corporation that can invest domestically in strategic areas such as artificial intelligence and data centers. How this compares internationally - The Korean approach differs from the US, where the IRS typically treats digital assets as property and allows taxpayers to use capital losses to offset gains (subject to tax rules). Without loss carryforwards in the Korean framework, active traders may face a less flexible tax position than their US counterparts. US-based or other foreign investors who use Korean platforms should watch for any exchange changes to access, product offerings or reporting requirements ahead of 2027. What domestic exchanges and taxpayers should do now - Exchanges will need to prepare reporting infrastructure and compliance processes ahead of the tax’s start date. Lawmakers could still change the rules — particularly around loss treatment or repeal — before 2027, but unless the National Assembly intervenes, the 22% levy will take effect on Jan. 1, 2027. Key facts at a glance - Effective date: Jan. 1, 2027 - Tax rate: 20% national + 2% local = 22% - Tax threshold: annual gains above 2.5 million won (~$1,740) - Filing: first returns due May 2028 for 2027 income - Current debates: no loss carryforwards, possible trading flight offshore, pending repeal bill and broader digital-asset legislation The coming months will be critical: exchanges prepare systems, lawmakers consider last-minute fixes, and market participants weigh whether Korea’s new tax rules will change trading behavior or spur migration to non-domestic platforms.
